我加载的线行在打开CAD的第一个文档视里起作用。。。如果新建一个一个文档（文档）就不起作用了

源码附上。。。大家帮帮

//CON1LINE  是我自己做的线形。。。

acdbHostApplicationServices()->workingDatabase()->loadLineTypeFile("CON1LINE","acadiso.lin");
 
 AcDbLayerTable *pLayerTbl;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pLayerTbl, AcDb::kForWrite);
    if (!pLayerTbl->has("ASDK_TESTLAYER")) {
        AcDbLayerTableRecord *pLayerTblRcd
            = new AcDbLayerTableRecord;
        pLayerTblRcd->setName("ASDK_TESTLAYER");
        pLayerTblRcd->setIsFrozen(0);// layer to THAWED
        pLayerTblRcd->setIsOff(0);   // layer to ON
        pLayerTblRcd->setVPDFLT(0);  // viewport default
        pLayerTblRcd->setIsLocked(0);// un-locked
  
        AcCmColor color;
        color.setColorIndex(1); // set color to red
        pLayerTblRcd->setColor(color);
  
        // For linetype, we need to provide the object ID of
        // the linetype record for the linetype we want to
        // use.  First, we need to get the object ID.
        //
        AcDbLinetypeTable *pLinetypeTbl;
        AcDbObjectId ltId;
        acdbHostApplicationServices()->workingDatabase()
            ->getSymbolTable(pLinetypeTbl, AcDb::kForRead);
        if ((pLinetypeTbl->getAt("CON1LINE", ltId))
            != Acad::eOk)
        {
            acutPrintf("\nUnable to find DASHED"
                " linetype. Using CONTINUOUS");
           
            // CONTINUOUS is in every drawing, so use it.
            //
            pLinetypeTbl->getAt("CONTINUOUS", ltId);
        }
        pLinetypeTbl->close();
  
        pLayerTblRcd->setLinetypeObjectId(ltId);
        pLayerTbl->add(pLayerTblRcd);
        pLayerTblRcd->close();
        pLayerTbl->close();
    } else {
        pLayerTbl->close();
        acutPrintf("\nlayer already exists");

起码基本功不扎实,除了“CONTINUOUS”，其他线型是不会自动加载到每一个新建的文档中的。

将你上面的程序写到一个过程中，再在On_kLoadDwgMsg中调用。。。

acdbHostApplicationServices()->workingDatabase()当前工作的文档数据库

acdbHostApplicationServices()->workingDatabase()指当前工作的文档数据库
